The card itself works and is supported in "new" linuxes. When i was running fedora previously, it worked, and when I boot some live ubuntu it also works.
On CentOS however, it does not work. Why is that so, and can I fix it?
I wouldn't be surprised when there simply are no drivers (yet) for it, but lsusb and KInfocenter (I'm on a KDE system) "see" the card, but I can't see an option for mobile broadband in the networking "widget" in my panel and "mobile broadband" is greyed out in the settings.
Searching around a bit, it seems like ModemManager ought to be responsible for modems, but according to https://www.freedesktop.org/wiki/Softwa ... #index20h1 mine isnt supported anyways. (What's driving that modem then in other distros where it does work?)
However, at first it seems that it does recognize a Sierra modem, successfully creates it…
